drift excursion
English
[edit]
Etymology
[edit]Originally a reference to the excursion or deviation of a sea vessel from its course due to drift resulting from tides, wind, etc., this term has been generalized to refer to any deviation in position due to outside forces.
Noun
[edit]drift excursion (plural drift excursions)
- The movement of something (such as a vehicle, structure, or charged particles) from its intended course or position due to outside forces.
- 1966, Carl A. Wagner, The Earth's Longitude Gravity Field as Sensed by the Drift of Three, page 89:
- A very close approximation to the geographic drift excursion in a resonant gravity field of a 24-hour satellite follows the differential equation of motion, Equation 2, (see also Reference 2) and is, evidently, given by an elliptical integral such as that developed in Appendix E of Reference 3.

- A collision changes the detailed nature of the particle orbit in a time which is very short compared to the time required to traverse magnetic field scale lengths, thus producing a step across flux surfaces the size of the orbit drift excursion away from the flux surface .

- The bidirectional drift excursion for the beam-column joint is applied in the anticlockwise direction as per the numbering sequence illustrated in Figs. 8a and 8b.
